@wanglone you're right.

@jujujijijaja At synchronous speed the rotor current has to be DC, as in ordinary synchronous machines. If the shaft speed is above or below synchronous speed, the rotor current must be AC at the slip frequency.

One quick question, when you have exactly sinchronus speed, you have DC on the rotor windings right? or do you have no current at all?

I can see the frequence of the rotor current changed with the rotor speed, is that right?
